Majumder, B.Mukherjee, J.Kandasamy, K.Ray, K.P.2026-02-0620182017 IEEE International Conference on Antenna Innovations and Modern Technologies for Ground, Aircraft and Satellite Applications, iAIM 2017, 2018, Vol., , p. 1-4https://doi.org/10.1109/IAIM.2017.8402618https://idr.nitk.ac.in/handle/123456789/31353In this paper a simulation based study of a novel continuously beam steerable antenna is presented using a tunable metasurface as phase varying reflector. The antenna radiation pattern can be changed by changing the state of the diodes loaded in the phase varying reflector. A planar dipole antenna is used to excite the tunable reflector. By this technique the antenna beam can be steered from +300 to -300 in the broadside direction depending on the operating state of the diodes. Moreover, the state of the diodes can be addressed digitally and hence a steep gradient in phase can be achieved in the reflector. The antenna radiation pattern and the gain has been found stable all over its states. © 2017 IEEE.
